Abstract
Abstract IN THE PREPARATION OF A CATALYST OF A GROUP VIII METAL COMPONENT AND A DECATIONISED ZEOLITE, THE DECATIONISED ZEOLITE IS AGED IN WATER FOR AT LEAST 1 WEEK, PREFERABLY AT LEAST 3 WEEKS, BEFORE BEING CONTACTED WITH A SOLUTION CONTAINING GROUP VIII METAL CATIONS. THE METHOD ASSISTS IN OBTAINING EVEN DISTRIBUTION OF THE GROUP VIII METAL THROUGHOUT THE ZEOLITE WHILE USING A MINIMAL EXCESS OF GROUP VIII METAL CATION IN THE CONTACTING SOLUTION. THE PREFERRED ZEOLITE IS MORDENITE. THE CATALYST MAY BE USED FOR HYDROCARBON CONVERSION, E.G., HYDROCRACKING, HYDROGENATION, DEHYDROGENATION, DISPROPORTIONATION ISOMERISATION, AND SELECTIVE CRACKING OF N-PARAFFINIC HYDROCARBONS.
